Setting up the planing knives fig. 16a, b, c
• The HSS planing knives are inserted in the
factory and set up correctly.
If required, you can re-do the settings or refine
them as described.
• Adjust one planing knife after the other.
• Set the position of the planing knife using the
setting screws alternatively until the blade
of the knife touches both perfectly trimmed
boards (used as adjustment gauge) which
are placed on the unloading table.
• Set the loading table to a dressing height of
2 mm.
• Rotate the cutterblock until the knife has
reached the maximum height.
• The planing knives are positioned on the
head of the setting screws in the slot of the
cutterblock. Let the knives touch the boards
by unscrewing the setting screws with an
Allen key.
• Align the knife support and check the position
of the knives again.
• Checking the knives
Put a trimmed board (adjustment gauge) on
the unloading table and mark the position of
the board.

1. Irregular and interrupted
transport during
thicknessing
2. Work piece ledge during
jointer work
3. Work piece irregularity
during jointer work (hollow,
crowned)
Electrical maintenance work may be carried out only by a qualified electrician!
When disposing of the machine, local legal stipulations must be complied with.
By turning the cutterblock in the cutting direc-
tion by hand, the knife blade should move the
board by x = 2 to 3 mm. Carry out this check
for every knife on the operating side and on
the other side.
Without careful settings, the trimming cannot
be exact.
• Tighten the pressure screws on the v-ledge
with a flat spanner (8.9 N/m).
• Adjust all planing knives in the same way
and clamp them.
• Carry out a test-run after every knife repla-
cement and tighten the pressure screws
afterwards (8.9 N/m).
Before using the cutterblock, check if the inst-
ructions above were followed.
Before turning on the machine, the general
safety notices must be observed.

Clean the thicknessing table regularly and spray
it (lubricant). This applies particularly to damp and
resinous wood.

out with great care and by using the setting rule.
Adjust the stiff trimming desk 1 mm above the planing
shaft body, as well as parallel to the bottom plate.
